Objective Oxidative stress is triggered by malnutrition and antioxidant losses due to dialysis in hemodialysis patients and thus, oxidative stress increases the risk of mortality in patients with cardiovascular disease and obesity. The study aims to determine differences in cardiovascular risk scores and obesity indices between hemodialysis and control groups and to examine the relationship between the tertiles of dietary total antioxidant capacity with cardiovascular risk, and obesity in hemodialysis and control groups. Methods This is a cross-sectional case-control study involving hemodialysis patients (n=46) and healthy individuals (n=46). Participants' general characteristics were obtained via a questionnaire, and the Framingham Risk Score was calculated. The dietary total antioxidant capacity was calculated using two methods based on a seven-day food record. Obesity indices, such as Basal Metabolism Index and Body Shape Index, were calculated using anthropometric measurements. Results The mean age of the participants was 51.1 +/- 10.4 years. In the hemodialysis group, obesity indices including body weight, Basal Metabolism Index, waist circumference, fat mass index, and fat -free mass index were lower, while Framingham Risk Score values were higher than the control group ( p <0.05). Energy-adjusted dietary total antioksidant capacity values were lower in hemodialysis group, and most patients were in the low tertiles of Trolox equivalent antioxidant capacity, total radical -trapping antioxidant parameter, ferric reducing -antioxidant power and vitamin C equivalent antioxidant capacity ( p <0.05). Conclusion Providing hemodialysis patients with a healthy diet can increase the dietary total antioxidant capacity, and potentially reduce cardiovascular risk, and obesity indices.
